Primary users –
United States Army
United States Air Force

In 1947, the United States Army Air Forces (later the United States Air Force) ordered the improved Bell Model 47A. Most were designated YR-13 and three winterized versions were designated YR-13A. The United States Army first ordered Bell 47s in 1948 under the designation H-13. These would later receive the name Sioux.

Initially, the United States Navy procured several Bell 47s, designated HTL-1, between 1947 and 1958. The United States Coast Guard evaluated this model, and procured two HTL-1s for multi-mission support in the New York Harbor. The most common U.S. Navy version of the 47 was designated the HTL-4, and dispenses with the fabric covering on the tail boom. The U.S. Coast Guard procured three HTL-5s in 1952 (similar to the HTL-4 but powered by a Franklin O-335-5 engine) and used these until 1960. The Coast Guard procured two of Bell’s Model 47G and designated them HUL-1G in 1959.

The H-13 was one of the principle helicopters used by the U.S. Army during the Korean War, with the H-13D variant being the most prevalent. During the war it was used in a wide variety of roles including observation, reconnaissance, and medivac. It was also used as an observation helicopter early in the Vietnam War, before being replaced by the Hughes OH-6 Cayuse in 1966.

The Bell 47 was ordered by the British Army as the Sioux to meet specification H.240, with licensed production by Westland Helicopters. In order to comply with the terms of its licence agreement with Sikorsky Aircraft, which prevented it building a U.S. competitor’s aircraft, Westland licensed the Model 47 from Agusta, who had purchased a license from Bell. the first contract was for 200 helicopters. The first 50 helicopters of the contract were built by Agusta at Gallarate in Italy followed by 150 built by Westland at Yeovil. The first Westland Sioux made its maiden flight on 9 March 1965.

Blade Nano CPX/S – A Beginner’s Introduction To Collective Pitch Flying is designed to help beginner helicopter pilots in a few months transition from flying co-axial or fixed pitched helis to the more challenging and aggressive collective pitch helicopters. At first glance many beginner pilots think buying a CP helicopter and firing it up is just as easy as to fly as their first helicopter, but soon they discover that not only are CP helis faster than the mind can think but they can be very dangerous with careless use.

Blade Nano CPX/S – A Beginner’s Introduction To Collective Pitch will discuss all the basics, equipment needed, and flying skills required for the heli pilot that is looking to advance his flying experience. By using the Nano CPX/S you will find an economic and safe way to learn how to fly a collective pitch helicopter that will prepare you for flying 400-600 size class helicopters.

Bell 412 Scale R/C Helicopter Electric Power Conversion

A fast video clip clip demonstrating the starting sequence of the heli. The mechanics arranged started out ‘life’ as a Miniature Aircraft X-Cell sixty, initially driven by a .60ci glow (nitro) fueled motor. I engineered an electrical motor conversion to exchange the nitro engine which benefits in a really practical (turbine) starting effect, lower vibration and paint that isn’t really struggling from the deterioration of the gas and exhaust.

Vario Bell 412 R/C Helicopter Electric Conversion

The fuselage is a Vario Bell 412 painted in PHI (Petroleum Helicopters Inc) shades. Mechanics are Vario Skyfox personalized-transformed from a nitro motor to electric strength. Motor is a Kohler Actro 32-four, battery pack is 12S LiPo, 4900mAH. To let the 4-blade primary rotor take care of very easily in ahead flight and wind, a Helicommand gyro ‘virtual flybar’ is related on the cyclic. Flying weight is somewhere between 16-19lbs. The gradual windup of the rotor system is due nearly fully to the smart notion of leaving the original centrifugal clutch in the new electrical generate prepare. Blended with the programmed sluggish start off of the Castle Creations 85HV brushless motor digital pace manage and you now have a very shut simulation to a genuine gas turbine start – without the gasoline turbine price tag. The electric conversion is a product of Distinctive Aircraft, owned and operated by learn scale heli builder, Darrell Sprayberry.
